Abstract
The invention discloses a power output shaft lubricating system of a crawler tractor, which mainly comprises a gearbox assembly, a rear axle assembly, a power output shaft assembly, an oil inlet pipe assembly, a spray lubricating joint and an oil suction pipe assembly. The gearbox assembly is connected with the rear axle assembly through a bolt, the rear axle assembly is connected with the power output shaft assembly through a bolt, the spray lubricating joint is screwed on the upper part of the power output shaft assembly, the oil inlet pipe assembly is connected with the spray lubricating joint through a hollow bolt, and the oil suction pipe assembly is connected at the lower half part of the rear axle assembly through a flange. The box body lower part of the gearbox assembly and the box body lower part of the rear axle assembly are provided with through holes A, and the box body upper part of the rear axle assembly and the box body upper part of the power output shaft assembly are provided with through holes B. The lubricating system has compact structure and reasonable part configuration, solves the problems that the crawler tractor cannot be lubricated or cannot emit heat when transferring high power in a small power output shaft shell due to the limitation of the structure, and improves the working reliability of the power output shaft of the tractor.
Description
Technical field
The invention belongs to the trac. field, relate to a kind of crawler-tread tractor power take-off shaft lubricating system.
Background technology
At present, at home on the crawler-tread tractor of Sheng Chaning, mostly adopt non-lubricating type takeoff output axle construction, this structure is owing to be subjected to the restriction of rear suspension rod member, the takeoff output shaft housing can not increase by actv., make that takeoff output axle assembly load-carrying capacity is less, power take-off shaft easily generates heat, and reliability is relatively poor.In addition, along with the increase in demand of market, require to improve constantly the power of crawler-tread tractor to large tractor., improving constantly of crawler-tread tractor take-off output can make the heating phenomenon of power take-off shaft more and more serious, influenced the reliability of service of trac..
Summary of the invention
The object of the present invention is to provide a kind of economic and practical, dependable performance, can guarantee the normal lubricating system that uses of crawler-tread tractor power take-off shaft.
Technical scheme of the present invention is: a kind of crawler-tread tractor power take-off shaft lubricating system mainly comprises: transmission assembly, back axle assembly, takeoff output axle assembly, oil inlet assembly, spray lubrication joint, oil suction pipe assembly; It is characterized in that: transmission assembly and back axle assembly pass through bolted connection, back axle assembly and takeoff output axle assembly pass through bolted connection, the spray lubrication joint is screwed onto takeoff output axle assembly top, the oil inlet assembly is connected by hollow bolt with the spray lubrication joint, and the oil suction pipe assembly is connected the back axle assembly lower part by flange.
The lower box of transmission assembly and the lower box of back axle assembly are provided with intercommunicating pore A, and the casing top of back axle assembly and the casing top of takeoff output axle assembly are provided with intercommunicating pore B.
The present invention takes can reach following beneficial effect after the technique scheme:
This crawler-tread tractor power take-off shaft lubricating system, compact conformation, parts configuration are rationally, solved crawler-tread tractor because the restriction of self structure, can't lubricate and heat-producing problem when transmission is more high-power in less takeoff output shaft housing, improve the reliability of tractor motive power output shaft work.Low cost of manufacture of the present invention, performance is safe and reliable, and is good with existing crawler-tread tractor matching of producing, and realized the spray lubrication of crawler-tread tractor power take-off shaft effectively, reduced the manufacturing cost and use cost of trac. complete machine.
Description of drawings
Accompanying drawing is the constructional drawing of crawler-tread tractor power take-off shaft lubricating system of the present invention.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.As shown in drawings, crawler-tread tractor power take-off shaft lubricating system comprises: transmission assembly 1, back axle assembly 2, takeoff output axle assembly 3, oil inlet assembly 4, spray lubrication joint 5, oil suction pipe assembly 6.Transmission assembly 1 is passed through bolted connection with back axle assembly 2, back axle assembly 2 passes through bolted connection with takeoff output axle assembly 3, spray lubrication joint 5 is screwed onto takeoff output axle assembly 3 tops, oil inlet assembly 4 and spray lubrication joint 5 are connected by hollow bolt, and oil suction pipe assembly 6 is connected back axle assembly 2 lower parts by flange.The lower box of the lower box of transmission assembly 1 and back axle assembly 2 is provided with intercommunicating pore A, and the casing top of back axle assembly 2 and the casing top of takeoff output axle assembly 3 are provided with intercommunicating pore B.
Transmission assembly 1 is communicated with the casing intercommunicating pore A of back axle assembly 2 bottoms with the casing of back axle assembly 2 by transmission assembly 1 bottom, the casing top of back axle assembly 2 is communicated with by intercommunicating pore B with the casing top of takeoff output axle assembly 3, circulating lubricating oil enters in the takeoff output axle assembly 3 through spray lubrication joint 5 sprays by oil inlet assembly 4, excessive takeoff output spindle oil is in intercommunicating pore B flows into back axle assembly 2, again in intercommunicating pore A flows into transmission assembly 1, then by oil suction pump through 6 sucking-offs of oil suction pipe assembly, pressurize after oil inlet assembly 4 sprays to go in the takeoff output axle assembly 3 once more by force (forcing) pump, circulation once more, realization is to the gear of takeoff output axle assembly 3, bearing lubrication reduces the warm purpose of takeoff output axle assembly 3 oil.
During work, the pasta of takeoff output axle assembly 3 is higher than the pasta of back axle assembly 2, entering the unnecessary lubricating oil that sprays into through spray head 5 by oil inlet assembly 4 flows back to naturally through intercommunicating pore B, and the lubricating oils that the height of position, hole and hole size design can not occur in the back axle assembly 2 in the time of guaranteeing trac. upward slope, descending enter in the takeoff output axle assembly 3 in a large number, or the oil in the takeoff output axle assembly 3 enters in the back axle assembly 2 the dilatory function normal operation of assurance in a large number.
